SHINGIE.

Application filed April is, 1925. Serial No. 23,439.

This invention relates generally to shingles of the composition type.'

A general object of the invention isto provide a shingleof this generaltype in which member 11 is folded to the underturned position theangular or corner portions 12 will assume the form of lateral extensionswith present impervioussurfaces o-fa stable charrelation to the bodyportion of the taband will thus provide for the anchoring engagementreferred to with the previously laid adjacent shingles. Preferably theextreme downwardly extending corner portion of the tab 11 is removed toprovide'an edge 15 I the edgeportions exposed to the weather will a'cterresistant to the action of wind and rain. Another object of theinvention is to provide improved'means for 'anchoringthe lowerextremities ofthe shingles in position.

The invention consists of a shingle having an underturned corner tabportion cooperating with underturned edge portions on the portion of theshingle exposed to the weather to provide impervious and relativelythick and substantial edges. The corner tab portion is preferably soformed as to extend laterally under tlie edges of adjacent shinglesalthough the horizontal edge visible to an observer extends only fromedge toedge of the two adjacent underlying shingles.

Other" features of the invention will be hereinafter "referred to.

In the drawings in which a preferred embodiment of the invention hasbeen selected for illustration, r

Figure 1 is a plan view showing in assembled relation a group ofshingles embodying to the invention.

Figure 2 is a view in cross-section on the line 2+2 of Figure 1.

'Figur" 3 is a line in cross-sectionon the line 3-3 of Figure 1.

$5, Figure a face view of the under side of one of the shingles shown inFigure 1. I Figure 5 is a sectional view of the shingle shown in Figure4. L

Figure 6 is a detailed view showing a portion of a shingle before theedg'es arefolded.

12 in the tab member 11 the tab is initially,

formed as shown in Figure 6 of the drawing with side edges 13 formedsubstantiallyatrightangles to the side edges 1450f the-body portion; ofthe shingle 110; With this atrangement it willbe seen that when the taban'ample anchoring function is provi such as is clearly shown in Figures4 and 6 of the drawing.

In addition to the underturned corner portion 11, I provide for theturning under of the downwardly converging edge portions 13 of'thelowerhalf portion'of theshin le.

The purpose of this is to provide an un er- 7 I turnedand accordinglyimpervious surface for presentation to the weather, it being clear thatthe new edge portion 16 which is thus provided has the same impervioussurface finish thatis' characteristic of the outer face of the'main bodyportion of the shingle 10. 7

By thus doing away with the raw or cut edge which is characteristic ofthis general type heretofore known indoing away with the wear and tearto which such edges are subjectedunder the action of rain and wind.

'In addition to the resistance to weather and used I succeed which isprovidedby the turned edges 16,

a more stable construction in general is rovided in that the edgeportions of the ower part ofthe shin le have a double thickness. Anadditiona advantage of this construction resides in the attractive ap,pearance which is presented by the thickened edge lines with theaccompanying shadows to the attrac-j.

which contribute s'ubstantiall tiveness of a roof or swal protected byshingles oithis type. 1

It will beseen that the turned edges 16 are provided only on thedownwardly facing edges of the shingle and that the upper edges of theshingles remain in their flat or unturned condition. With this arranment there is no interlocking of the e ge portions 16 with theunderlying shingles nor is there need of any such interlockin ed. by

since the anchoring tab member 11 already referred to.
